True eradication of the view of self also requires contemplating the manas as not-self.

If the manas does not recognize the five aggregates as self and does not cling to the five aggregates, would the manas cling to itself? The manas makes itself into the self, into something real, and thus clings to its own decision-making nature without letting go—this is the function of the manas's self-validating cognition (svasaṃvedana). This view must also be eradicated; only then is there true eradication of the view of self (satkāya-dṛṣṭi). Therefore, when practicing contemplative practice (vipaśyanā-caryā) to eradicate the view of self, one must also contemplate that the manas is not self. Among the eighteen realms that are not self, the manas is one of the realms, and it too must be eradicated; only then is the view of self truly eradicated.
